Objective: To evaluate the results of nocturnal penile erection test and response to daily sildenafil in patients with erectile dysfunction(ED)due to pelvic fracture urethral disruption.Methods: In the past three years,we included 38 patients with ED due to pelvic fracture urethral disruption.The mean age was 33.1 years(range,22-49 years).All were evaluated subjectively and objectively by the International Index of Erectile Function-5,nocturnal penile tumescence and rigidity(NPTR)test,and penile Doppler ultrasonography.Patients received daily sildenafil 50 mg for 3 months.Results: Thirty-one patients were followed up: 54.8%showed response to sildenafil defined as reporting successful vaginal penetration and intercourse.Patients with neurogenic,arterial,and venous EDs did not differ in efficiency rates(P 1/4.587).However,the penile erectile rigidity recorded by NPTR test affected efficiency significantly(P 1/4.046).Patients with tip rigidity >40%had the highest response rate(76.9%),but the response rate for patients with tip rigidity <20%was only 22.2%.Conclusions: NPTR recording can reveal resident erectile function in patients with ED due to trauma and is significant for selecting pharmacologic treatment as optimal therapy.
